Recent observations have found a 1700 km/s star [S5-HVS1] that was ejected
from the Galactic Center approximately five million years ago. This star was
likely produced by tidal disruption of a binary. In particular, the Galactic
Center contains a young (few million years old) stellar disk that could excite
binaries to nearly radial orbits via a secular gravitational instability. Such
binaries would be disrupted by the central supermassive black hole, and would
also explain the observed cluster of B stars ~0.01 pc from the Galactic Center.
In this letter, we predict S5-HVS1 is part of a larger stream, and use
observationally motivated N-body simulations to predict its spatial and
velocity distribution.
